From Geneva University, a class to :
Convert WGS84 datum (gps) coordinates into topographics coordinates of another datum and inversely.
Class to translate and transform latitude and longitude coordinates (WGS84) to Northing (Coordinates Y) and Easting (Coordinates X) and inversely.
The translation model is done by the Molodensky Model.
The autors are : Praplan Christophe, Velen Stephane
That class should makes much easier the programming of J2ME applications that need to get coordinates or other informations from a Bluetooth GPS receiver.
